🚀 6+ Years of Experience | 🏅Top Rated MERN Stack Developer | 🌍 Trusted by Clients Worldwide
🔥 If you're here because your app is slow, your AI features are half-baked, or your previous developer disappeared mid-sprint, you've found the right person.
⚡I'm a Senior Full-Stack MERN Developer specializing in production grade AI powered web applications. Not ChatGPT wrappers. Not tutorial level integrations. I'm talking about RAG pipelines with semantic vector search, multi tenant SaaS architectures, and realtime fullstack systems that handle real traffic without falling apart.
💼 What I Build:
⚙️ AI-Powered Web Applications
• RAG pipelines with semantic chunking, embedding strategies & precise vector retrieval
• OpenAI / Claude API integrations
• AI knowledge bases, document Q&A systems & intelligent semantic search
• Vector databases: Pinecone, Weaviate, pgvector, chosen for your use case, not just familiarity
⚙️ Full-Stack MERN Development - full ownership from database to UI.
• MongoDB · Express.js · React.js · Node.js, built with clean separation of concerns
• REST APIs designed for scale, versioning & real-world edge cases
• WebSockets for real-time features, notifications, chat, live dashboards
• Redis caching for high-performance, low-latency backends
• TypeScript throughout, no more runtime surprises in production
🚀 Next.js SaaS Platforms - From idea to live product, built the right way.
• Multi-tenant Next.js 14/15 SaaS architectures

• Rebuilt a legacy Node.js API into a modular, Redis-cached service handled 10x traffic without infrastructure changes
🤝 Why Clients Keep Coming Back:
• I ask the right architecture questions before writing a single line, bad structure costs 10x more to fix later
• Will deliver clean, documented, maintainable code
• Proactive updates before you have to ask, no ghosting, no vague statuses
• I treat your deadline like my own reputation is on the line, because it is
• I take full ownership, you brief me once, I figure out the rest
📩 Send me your project. I'll respond within a few hours with a clear plan, no fluff, no vague estimates.
One conversation could save you months of fixing someone else's shortcuts.

Greetings!
Alex here - a London-based UX/UI Designer, Full Stack Developer, and AI-focused product builder.
I design, build, and optimise digital products with AI embedded across the full lifecycle - from research, UX, and interface design to development, automation, project delivery, and internal tooling. I also build custom AI solutions for my own workflows and help businesses implement AI in ways that are practical, commercially useful, and technically sound.
My work sits at the intersection of product thinking, full-stack execution, and applied AI. That includes everything from AI-assisted delivery and automation to more advanced AI development such as RAG systems, LLM integrations, fine-tuning workflows, machine learning implementation, and custom AI-powered product features.
Why work with me:
• Expert-vetted professional trusted to deliver high-impact work across design, development, and AI-led execution
• Top-Rated Plus with a strong track record of shipping thoughtful user experiences and reliable technical solutions
• Among the top 1% in design and development, with AI deeply integrated into how I work and what I build
• 99% of clients rate my work 5/5, reflecting consistent quality across strategy, execution, and communication
What sets me apart:
I combine design, engineering, and AI implementation in one end-to-end approach.
1. AI-enhanced design - I use AI to accelerate research, explore UX directions faster, test concepts, support content thinking, and improve design workflows without losing human judgement.
2. AI-supported development - I use AI across architecture, implementation, debugging, optimisation, QA thinking, and documentation to move faster while maintaining technical quality.
3. AI product development - I help build AI-native features and products, including chat experiences, AI assistants, internal copilots, recommendation flows, knowledge systems, and automation tools.
4. LLM and RAG expertise - I work with retrieval-augmented generation systems, document-aware AI workflows, vector-based search, prompt architecture, context pipelines, and knowledge-grounded assistants.
5. Machine learning and fine-tuning - I understand how to approach model selection, fine-tuning workflows, dataset preparation, evaluation logic, feedback loops, and practical ML implementation where it genuinely adds value.
6. AI for operations and project management - I apply AI to planning, task structuring, documentation, QA workflows, communication, and internal process efficiency.
7. Custom AI tooling - I develop my own AI-powered tools and workflows and help others create bespoke AI systems tailored to their teams, products, and business models.
8. Holistic execution - design, engineering, AI, and delivery are handled as one connected system, reducing friction and improving outcomes.
Clear communication, transparency, and quick responsiveness remain central to how I work. AI improves the process - it does not replace ownership, thinking, or quality control.
What you’ll get from me:
• UX/UI design shaped by product thinking and accelerated by AI-assisted workflows
• Full-stack development with strong technical foundations and modern delivery methods
• Practical AI integration into products, operations, and internal workflows
• Support with RAG systems, LLM-based features, fine-tuning direction, ML-related implementation, and AI automation
• End-to-end ownership from discovery and prototyping through to development, launch, and iteration
Technical toolbox:
UX/UI & Product Design
• Figma, Sketch, Adobe XD, InVision
• Wireframing, prototyping, user flows, usability testing
• AI-assisted design exploration, research synthesis, and workflow acceleration
Frontend Development
• React.js, Next.js, Vue.js, JavaScript (ES6+), TypeScript
• HTML5, CSS3, Tailwind, BEM, jQuery
Backend Development
• Node.js, Express, Python, Django, DRF, PHP, Laravel, Ruby on Rails
• REST APIs, GraphQL
• Backend architecture for AI features, automations, and internal tools
AI Development
• LLM integrations and AI application development
• RAG systems and document-aware assistants
• Prompt engineering and context orchestration

With 8 years of hands-on experience across full stack web development and scalable digital systems, I help UK and US businesses turn ideas into fast, reliable, and commercially successful web products.
I've worked across the complete product lifecycle — from the first technical conversation with a client all the way through to deployment, testing, and ongoing support. That means when you hire me, you're not just getting someone who writes code. You're getting someone who thinks about your project from a business perspective: what it needs to do, who it's for, how it needs to scale, and how it needs to perform when real users are actually using it.
Over 8 years, I've built production-grade applications at BairesDev — one of the world's leading software outsourcing agencies, trusted by Fortune 500 companies — and at CHOPDAWG, a US-based digital product agency known for building high-quality web and mobile products for startups and growth-stage businesses. This track record means I bring enterprise-level discipline and standards to every freelance project, regardless of size.

━━━━━━━━━━━━━━━━━━━━━━
WHO I WORK BEST WITH
━━━━━━━━━━━━━━━━━━━━━━
I work best with UK and US businesses who know what they want to build but need a technically strong, reliable developer to bring it to life. Whether you're a startup launching your first product, a growing business replacing a legacy system, or an established company adding new features to an existing platform — I can step in, get up to speed quickly, and deliver.
I particularly enjoy projects where the brief isn't fully defined yet. I'm comfortable helping you think through the architecture, the right tech stack choices, and the most efficient way to build what you need — not just executing a spec blindly.
━━━━━━━━━━━━━━━━━━━━━━
I have built web applications used by real users, integrated complex APIs across multiple business systems, and collaborated with cross-functional teams across different time zones and cultures. Every project I take on gets the same level of focus, care, and professionalism — whether it's a $500 fix or a $50,000 platform build.
If you're looking for a developer who brings both deep technical skill and genuine professional reliability to your project — send me a message. I'd be happy to review your brief and tell you honestly whether I'm the right fit.
